Composite high-stability foamed light soil foaming agent and preparation method thereof

The invention discloses a composite high-stability foamed light soil foaming agent and a preparation method thereof. The foaming agent belongs to light construction material additives. According to the foaming agent disclosed by the invention, a surface active substance and an animal protein are modified, so that the foaming rate is increased, and meanwhile, by introducing different types of foamstabilizers and functional additives, the liquid surface expansion can be reduced, the foam stability can be improved, and functions and application environments of the foaming agent can be widened. The composite high-stability foamed light soil foaming agent comprises the following components in parts by mass: 5-15 parts of a cattle hoof animal protein, 1-3.5 parts of a foam stabilizer, 8-12 parts of an anionic surfactant, 1-4.5 parts of a thickening agent, 0-2 parts of a low-temperature early strength agent, 0-2 parts of an anti-freezing agent and 90-100 parts of water. The foaming agent iscapable of ensuring foam s
